I'm working on a Debian Live lenny image to use as a netboot rescue image on
failed machines.
I'm using live-helper 2.0~a7-1:
lh config -a amd64 -d lenny -b net --hostname lenny-live-amd64 \
--net-root-server 172.16.5.212 \
--net-root-path /vol/misc/debian-livecd-root/lenny-amd64
with this PXELINUX stanza:
LABEL lenny-live
kernel debian-live/amd64/vmlinuz-2.6.26-2-amd64
append debug=y initrd=debian-live/amd64/initrd.img-2.6.26-2-amd64
boot=live hostname=lenny-live-amd64 union=aufs netboot=nfs
nfsroot=172.16.5.212:/vol/misc/debian-livecd-root/lenny-amd64
Machines TFTP the kernel and initrd just fine, but the kernel panics during
the attempt to mount the root filesystem:
set_usplash_timeout
[ -x /sbin/usplash_write ]
[ -x /sbin/splashy_update ]
[ ! -z nfs ]
do_netmount
rc=1
modprobe -q af_packet
[ -x /sbin/udevadm ]
udevadm trigger
udevadm settle
[ 4.694059] Kernel panic - not syncing: Attempted to kill init!
I can mount the nfsroot= filesystem just fine, and it contains
live/filesystem.squashfs:
[[email protected]:pts/0 ~> mkdir r
[[email protected]:pts/0 ~> sudo mount
172.16.5.212:/vol/misc/debian-livecd-root/lenny-amd64 r
[[email protected]:pts/0 ~> ls -l r
total 12
drwxr-xr-x 3 root root 4096 2010-02-19 16:01 doc
drwxr-xr-x 2 root root 4096 2010-02-19 16:01 live
-rw-r--r-- 1 root root 2585 2010-02-19 16:01 md5sum.txt
[[email protected]:pts/0 ~> ls -l r/live
total 92692
-rw-r--r-- 1 root root 94699520 2010-02-19 16:00 filesystem.squashfs
-rw-r--r-- 1 root root 16664 2010-02-19 16:01 packages.txt
-rw-r--r-- 1 root root 2556 2010-02-19 16:01 parameters.txt
The same 'lh config' invocation (with '-b iso' instead of '-b net') produces
a working ISO image that will boot.
Perhaps 'udevadm settle' in /scripts/live is failing and the errexit
('set -e') is causing /init to exit? What am I missing?
